The serial number is 778,671. I consider this to be a relatively easy playing instrument from top to bottom. The action is solid and smooth and the tone is full and rich. Many of those that reviewed the 613 made the same conclusion. Incidentally, I played it with my own Selmer mouthpiece and ligature, not the King that is included with the sale.
The finish, as the photos show, shows some minimal, nearly indiscernible scratches and no dents. The pads are in overall, good condition.
The case is very sturdy and completely functional including all hinges and latches. Suffice it to say, if I continued to own it, I would not be afraid to use it in our community band.
